Abstract

Dickey & Thompson (2004) present evidence that individuals with agrammatic Broca’s aphasia retain significant on-line gap-filling capacity, which improves in response to linguistically-motivated treatment (TUF; Thompson 2001). This paper presents data from an eyetracking study following up this result. Twelve agrammatic aphasic individuals’ and eight control participants’ eyes were tracked while they listened to stories ending with comprehension probes involving wh- movement (wh- object questions, object clefts). Aphasic participants’ responses to probes demonstrated impaired comprehension of wh- movement structures. However, their eye-movements indicated intact automatic processing of the movement sentences, even for wh- questions which they failed to comprehend.
